  34
  35             This is a helper class which encapsulates geometry that should be
  36             painted XOR, e.g. old cursor visualisations. It decomposes to
  37             its content, so when not supporting it, the contained geometry
  38             will be visualized normally.
  39             Unfortunately this is still needed, but hard to support on various
  40             systems. XOR painting needs read access to the target, so modern
  41             graphic systems tend to not support it anymore.
